Embodiment 2

[0038] Embodiment 2: This embodiment is a further improvement of the previous embodiment: in this embodiment, the first motor 6 is used to replace the first motor 6 to drive the mechanism for the left and right movement of the adjustment seat 9, and the telescopic end of the electric telescopic rod is fixedly connected to the adjustment seat 9 , The structure of the electric telescopic rod is simpler, the transmission efficiency is more direct, and it is also worth promoting.

[0039] The working principle of the present invention is: the present invention controls the rotation of the first motor 6 through the remote control device when in use, the rotation of the first motor 6 drives the first transmission screw 7 to rotate, and the rotation of the first transmission screw 7 can drive the adjustment seat 9 to move left and right, The direction of motion is controlled by controlling the rotation direction of the first motor 6, thereby realizing the left and right adjustment of ...

Abstract

The invention discloses hoisting equipment for a bridge, and belongs to hoisting equipment. The hoisting equipment comprises an upper cross beam, four supporting beams and a sliding base, rotating connecting bases which are symmetrically arranged front and back are fixedly connected to the two ends of the upper cross beam correspondingly, the upper ends of the supporting beams are connected with the rotating connecting bases in a rotating mode correspondingly, a first motor base is fixedly connected to the left side of the lower portion of the upper cross beam, a first motor is fixedly connected to the lower portion of the first motor base, a first transmission screw rod is fixedly connected to an output end of the first motor, the outer side of the first transmission screw rod is in threaded connection with an adjusting seat, and a guide sliding groove is formed in the lower portion of the upper cross beam. The hoisting equipment is simple in structure and convenient to use, during use, the first motor, a second motor and a third motor are controlled to rotate forward and reversely through a wireless remote control switch, so that the hoisting position is driven by the first motorto move left and right, an object to be hoisted is hoisted and placed down by the second motor, the highest limiting height of hoisting is adjusted through the third motor, so that the bridge equipment can be more conveniently hoisted, and the use experience is better.

Description

technical field [0001] The invention relates to a lifting device, in particular to a lifting device for a bridge. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. Also known as crane, aerial crane, crane. [0003] Some working characteristics of lifting equipment are intermittent movements, that is, in a working cycle, the corresponding mechanisms for retrieving, moving, unloading and other actions work alternately. The development and use of cranes in the market are becoming more and more extensive. [0004] In the process of bridge construction, it is often necessary to hoist materials such as silt concrete, steel pipe fittings, etc. from a low place to the bridge through hoisting equipment. The traditional manual cable hoisting is time-consuming, labor-intensive, poor in stability and slow in speed. [0005] For this reason, the Chinese patent (authorized...
